Induction holding furnace

Plant for the inductive heating of molten metals. Eddy currents, which are generated by an alternating electromagnetic field, are induced in the molten metal to be kept warm and thus keep it warm due to its electrical resistance. The basic furnace type in the foundries is the induction channel furnace.

Fig. 1 (FOMET) shows the operating principle of this type of furnace.
